Ask students which earthquakes they remember hearing about in the news during the past few years. What were the effects of these earthquakes? What lessons might these earthquakes teach us to help us better prepare for future ones? Hold a brief class discussion on these questions.

2.

Inform students that the San Francisco Bay area has suffered from serious earthquakes and is at high risk for another major earthquake. Tell them that their goal in this lesson, after some preliminary research, will be to present to San Francisco Bay area politicians, construction engineers, architects, and geologists the lessons they should learn from previous earthquakes around the world.

3.

If students haven’t already studied earthquakes, have them use the Internet and/or the library to find background information about earthquakes, such as the answers to the following questions:

Why do earthquakes occur?

What happens underground during an earthquake?

What happens above ground during an earthquake?

Where do earthquakes tend to occur? Why do earthquakes occur in these areas?

4.

Write the following occupations on the board:geologist,construction engineer/architect, andpolitician. As a class, define these occupations and discuss the different roles of each in earthquake planning and recovery. What kind of information would help people in each occupation prepare for an earthquake? Tell the class that they’ll be conducting research on past earthquakes or on current earthquake preparedness in the San Francisco Bay area.

5.

Divide the class into small groups of approximately four students each. Have all but one of the groups use the library and/or the Internet to find out about different major earthquakes that have occurred in the past 20 years. Some earthquakes to research include the Loma Prieta (San Francisco Bay area), Northridge (Los Angeles), Kobe, and Turkish quakes. Ask them to answer the following questions:

Why did an earthquake occur here? Is this city in a major fault zone?

How severe was this earthquake? What was its ranking on the Richter scale?

How did this earthquake affect people’s lives in the region?

What was the quality of construction in the region? How did buildings and other structures fare in the quake?

How prepared was this city for an earthquake? What evidence is there to support your answer?

How did politicians react to the earthquake?

What do geologists or others say should be done to prepare this city for another earthquake?

6.

Have the remaining group research and take notes on the current earthquake situation in the San Francisco Bay area. This group should address the following questions:

How great an earthquake risk does the Bay Area face?

What is being done to prepare for such an event? How are geologists, construction engineers and architects, and politicians working together (or not working together)?

What do geologists think should be done, assuming cooperation from the politicians and adequate funding?

7.

Stage a class forum in which the last group (the one that studied San Francisco’s current risk) pretends to represent San Francisco Bay area politicians, construction engineers, and geologists. The roles can be divided within that group. Have each of the other groups explain to the San Francisco group (and the rest of the class) the lessons that should be learned from the earthquake it has researched. Ask the members of the San Francisco group to reply with information on Bay Area geology and earthquake preparedness and to explain how they think the new information can help them become better prepared. At the end of the forum, each group will have presented the major points of its research, and the San Francisco group will have informed the class as to its research on the Bay Area earthquake situation.

8.

Now that they’ve learned about specific earthquakes, ask students to consider the ways in which the three professions listed on the board interact with each other to prepare for and recover from earthquakes. Hold a class discussion on this topic, using the following questions as guidelines:

What role do geologists play in studying earthquakes?

Why do construction engineers and architects need to be familiar with earthquakes? Do they always take geologists’ recommendations when designing buildings and structures? Why or why not?

What role do politicians play in the discussion of earthquakes? How do political factors affect the roles of geologists and construction engineers or architects? Do politicians always base their decisions on geologists’ recommendations?

How do these three professions work together for earthquake preparedness and in the aftermath of an earthquake? How effectively did they work together in past earthquakes, and how should they work together in the San Francisco Bay area today?

Adaptation for younger students (Grades 6-8)Have each group research one major earthquake, such as the Loma Prieta in the San Francisco Bay area or the Northridge quake in Los Angeles. How did the earthquake affect people’s lives? Was the community prepared for such an earthquake? Have students create an “Earthquake Preparedness” poster or brochure explaining what people should know about earthquakes in order to be well prepared. Include information about how individuals and families can prepare for an earthquake.

Discuss the role that political factors play in determining how cities and regions prepare for and react to earthquakes.

2.

Hypothesize what would happen in your town if geologists suddenly announced that a severe earthquake was highly probable in the next 20 years. How do you think the town leaders and the public would react? If this is a realistic situation for your town, what have the reactions been so far?

3.

How important do you think it is for the construction industry to develop materials and techniques to make buildings and other structures safe during earthquakes? What if these developments are extremely expensive? Should they still be implemented?

4.

Do you think it’s important to study historical events, such as past earthquakes, to learn how to handle events in the present and the future? How does learning about past events help us in the present and the future?

5.

Hypothesize the effects of a major earthquake in different parts of the world based on your knowledge of political situations, construction materials, and other factors in various countries. Would an earthquake that ranks 6.5 on the Richter scale, for example, affect regions in the same way, or would the effects be different depending on the location?

6.

What types of things do you think the public should be taught about earthquakes? Discuss the things you’ve been taught, and assess whether you think you’ve learned enough about earthquakes in your schooling and from the media.

Amnesia or Insight?Have students research San Francisco’s political history with regard to earthquakes and construction, including the reasons that the city was developed in a major fault zone. Ask them to write paragraphs explaining whether they think San Francisco has learned from its past mistakes or whether it is repeating them.

What Was It Like?Find someone who has been through a serious earthquake and invite that person to speak to the class about his or her experience. Have students ask questions about what the earthquake felt like, how structures held up, and how the city dealt with the earthquake’s aftermath. If your class or individual students have been through an earthquake, have them discuss their own experiences.

Magnitude 8: Earthquakes and Life Along the San Andreas FaultFradkin, Philip L., New York: Henry Holt, 1998Magnitude 8 is a history of earthquakes in the San Andreas Fault with the inclusion of other major earthquakes around the world. Fradkin uses human and natural disasters to tell the story of how suddenly, and unexpectedly earthquakes occur. He cautions that when the magnitude 8 earthquake occurs, which it will along the San Andreas Fault, it is up to the individual to be prepared.

Earthquake Country: How, Why & Where Earthquakes Strike in CaliforniaIacopi, Robert L., Tucson, AZ: Fisher Books, 1996This book is intended only to explore the nature of earthquakes in California, although it makes comparisons to other quakes around the world. The text is supported by informative maps and photos to illustrate scientific concepts.

The World-Wide Earthquake LocatorA geographical information resource for schools, developed by the Department of Geography, University of Edinburgh. The "locator" accesses data at the National Earthquake Information Center in Colorado and provides maps which can be saved to a web browse.

Geology Labs On-LineWeb-based lab activities for high school and above. Examples: Virtual Earthquake; Virtual Plate Tectonics. Could provide model for development of activities for younger grade levels, also.

USGS (United States Geological Survey)Lesson plans and resources for teachers, across the grade levels. Emphasis on "hands-on" learning and the use of technology tools. USGS offers a wealth of resources re: the study of earthquakes and related phenomenon.

Definition:A minor earthquake preceding a larger one that occurs at or near the same place.Context:A small earthquake may be an isolated incident, or it may be a foreshock of a larger earthquake in the near future.

Definition:The processes that cause changes and movement within the Earth’s crust.Context:The existence of earthquake zones, such as the San Francisco Bay area, makes sense when one considers the theory of plate tectonics; the Bay Area is at the junction of two of the Earth’s tectonic plates.

Definition:Of or caused by an earthquake.Context:The San Francisco Bay area is a “hot spot” for seismic activity; there are many earthquake faults in the region, posing a serious risk for a major earthquake in the near future.
